Wear Resistant Coatings Reduce Particulate Contamination in a Magnetic Disk Drive
A test was performed to evaluate the particulate contamination coming from components in a magnetic disk drive. The 300-series stainless steel components undergo unlubricated sliding motion and are susceptible to adhesive wear and fretting. To reduce the wear debris, the components were coated with six different hard coatings: electroless nickel, chromium, Nedox®, titanium nitride, amorphous diamond, and iron boride. Hardware was tested in a specially made chamber that permitted collection of the airborne particles on nucleopore filters as well as real-time particle counts. Particle size distribution and elemental composition were provided by automated image analysis using SEM and EDX.
